Squeezing the most accuracy out of your 300 Blackout AR Pistol means investing in the best barrel steel and fabrication process on the market - and that would be our 7.5" Heavy Stainless Pistol Barrel. Featuring industry-leading 416R stainless steel with CNC-cut rifling under ISO 9002 quality control standards, few barrels on the market can compare to the accuracy and reliability of our 300 Blackout Stainless Pistol Barrel here. With a 1:8 twist rate, this barrel easily accommodates and reliably cycles both subsonic and supersonic 300 Blackout loads with a universal 5/8 x 24 thread pitch for easy suppressor attachment.

Superior Quality and Accuracy

We combined plenty of manufacturing innovations to create what we think is the most accurate 300 Blackout Pistol Barrel you'll find. First, each barrel starts as a pure 416R stainless blank that is cut to precision specifications. Each barrel undergoes individual inspection to ensure every rifling land and groove is uniform and perfect. Our heat treating process hardens the rifling to a hardness rating or RC 28 to 32, providing superior consistency and resistance to wear, no matter the grain count you're shooting. A stress relieving process and heavy profile balance rigidity and barrel life.

We Use Only the Best Steel

All that fabrication work means nothing if it's done on subpar steel. Many stainless barrel manufacturers skip the quality component of their raw steel, using regular 416 or 410 stainless. These metals feature more impurities and provide less machinability, making for a less accurate AR Pistol. We use 416R because of its purity. With a lower sulfur content, this barrel resists developing weak points and rifling deformities over time. Performance is also more consistent across different temperatures and environments, though we still keep costs down to provide you the best value and literal bang for your buck.
